In addition to what we publish, we also offer the full rankings data for sale in the Plastics News Store.

If you work for a company that is missing from the ranking, we would like to include you next time. The listing is free. Just send a note to Hollee Keller at hkeller@crain.com or mail your information to Plastics News, Editorial Department, 1725 Merriman Road, Akron, Ohio 44313.

Thanks to Lisa Pyles for today's peek behind the data – and to Lisa Pyles and Hollee Keller for their research on this year's project.
